In high-end manufacturing fields such as fine chemicals, pharmaceuticals, agrochemicals, and new materials, product purity directly determines its value and market competitiveness. Inorganic salts, residual catalysts, and acidic or alkaline impurities remaining in the reaction system are like “grains of…

In today’s rapidly growing printed circuit board (PCB) industry, the etching process, as the core production stages, generates large volumes of waste etching solution rich in copper ions. If discharged directly, these waste liquids not only lead to a significant…

During pesticide production, the discharged wastewater often contains high concentrations of phthalic acid and other benzene derivatives. This type of wastewater is complex in composition, highly toxic, and poorly biodegradable. Traditional treatment methods are costly and make resource recovery difficult.…

In the production and research of fine chemicals, pharmaceuticals, and environmental protection industries, efficient separation is a key factor determining product quality and process success. Addressing the shortcomings of traditional sedimentation and static stratification methods, such as low efficiency, incomplete…

In the metal processing, electroplating, and steel industries, the pickling is an essential process. However, the large volumes of acidic wastewater generated—containing heavy metals such as zinc and iron—have become a major challenge for enterprises in terms of environmental protection…

In the non-ferrous metal smelting industry, nickel is an indispensable strategic resource. However, during the pyrometallurgical process, a large amount of nickel smelting slag is produced, which still contains considerable amounts of valuable metals such as nickel and cobalt. How…
